## What it is
An MCP server and CLI that exposes Korea's Ministry of Government Legislation (법제처) open APIs — statutes, precedents, ordinances, treaties, and tax interpretations — as 9-10 tools for LLM assistants like Claude, Cursor, and ChatGPT. It adds citation verification, precedent validity (citator) checks, impact graphs, and point-in-time diffs to reduce legal hallucinations.

## Use cases
- search korean statutes and case law from claude
- verify llm legal citations against real statutes and precedents
- detect hallucinated legal references in ai answers
- compare a korean law across time points with automatic diff
- check whether a precedent is still good law
- find which ordinances or regulations a statute amendment affects
- look up national tax service interpretations via mcp

## When to avoid
- you need non-Korean legal systems or multilingual legal databases
- you need a standalone legal research UI rather than an MCP/CLI integration
- you need authoritative legal advice — this is a data retrieval tool, not a lawyer
